Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding auxiliary equipment technology, specifically an adjustable welding roller frame. Background Technology
[0002] Welding roller frames are core equipment used to assist in the welding of cylindrical workpieces (such as pipes and pressure vessels). By driving the workpiece to rotate at a uniform speed, they achieve precise butt jointing and continuous welding, significantly improving welding efficiency and process consistency. Their functions include automated control of rotation speed, bearing heavy workpieces (up to tens of tons), and adaptability to different diameter specifications. They effectively reduce manual labor intensity and welding defect rates, and are widely used in machinery manufacturing, energy equipment, and shipbuilding industries, playing a vital role in improving welding quality, ensuring production safety, and promoting automated manufacturing.
[0003] The existing technology has the following shortcomings: In the existing technology, the "Adjustable Welding Roller Frame" with the publication number CN207272586U "includes a base plate, on which an outer roller frame and an inner roller frame with the same structure for supporting the welding roller are arranged in parallel. The outer roller frame and the inner roller frame are movably connected to the base plate. An external adjustment mechanism for adjusting the position of the outer roller frame is provided on the base plate. An internal adjustment mechanism for adjusting the position of the inner roller frame is provided on the base plate. A driven support shaft is provided on the outer roller frame. An active support shaft is provided on the inner roller frame. The driven support shaft and the active support shaft are arranged at the same height and horizontally. The center lines of the driven support shaft and the active support shaft are parallel to each other."
[0004] The aforementioned structure can accommodate welding rollers of different diameters by adjusting the distance between the outer and inner roller frames as needed. However, when welding columnar structures, this structure lacks any clamping components for positioning, making it susceptible to vibration and displacement during machine processing, leading to incorrect welding positions. Furthermore, the structure uses a screw to adjust the spacing to accommodate rollers of different diameters, but the screw's rotation speed is slow, resulting in poor adaptability. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable welding roller frame, which solves the problems of insufficient clamping components, susceptibility to machine tool vibration, and poor adaptive capability of screw adjustment.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable welding roller frame, including a workbench, a control panel, a planar support, and a first motor. The control panel is disposed on the outside of the workbench, the planar support is disposed on the upper part of the workbench, and the first motor is disposed inside the planar support.
[0007] An adjusting rubber roller is provided on the side of the first motor, a support shaft is provided on the side of the planar support, a drive gear set is provided at the bottom of the workbench, and a double-end self-clamping mechanism is provided below the planar support.
[0008] The double-ended self-clamping mechanism also includes an extension block, a connecting rod, and a flexible limiting clamp. The extension block is fixedly connected to the side end of the double-ended self-clamping mechanism, the connecting rod is inserted into the side end of the extension block, and the flexible limiting clamp is movably connected to the other end of the connecting rod.
[0009] As a preferred technical solution of this utility model, the extension block, the connecting rod and the flexible limiting clamp are each provided in two sets, and are evenly distributed on both sides of the double-end self-clamping mechanism, wherein the flexible limiting clamp has an inwardly concave arc surface structure on the opposite side.
[0010] As a preferred embodiment of the present invention, the planar support is provided with a rectangular block structure at the contact position with the flexible limiting clamp, and the rectangular block is embedded in the bottom of the flexible limiting clamp.
[0011] As a preferred technical solution of this utility model, the drive gear set further includes a linkage gear, a synchronous pulley, a synchronous belt and a second motor. The linkage gear is provided with a shaft structure in the middle, and the linkage gear is movably connected to the bottom of the double-end self-clamping mechanism near the second motor through the shaft structure.
[0012] As a preferred embodiment of this utility model, the synchronous pulley is fixedly installed on the upper end of the linkage gear, and two sets of synchronous pulleys are provided. The synchronous belt is sleeved around the two sets of synchronous pulleys, and the second motor is movably connected to the bottom of the drive gear set.
[0013] As a preferred technical solution of this utility model, a rectangular groove structure of equal depth is provided at the position opposite to the flexible limiting clamp on the side end of the planar support.

[0015] Compared with the prior art, this utility model provides an adjustable welding roller frame, which has the following features:
[0016] Beneficial effects:
[0017] An adjustable welding roller frame includes an adjusting roller, a support shaft, a drive gear set, a synchronous pulley, a synchronous belt, and a double-end self-clamping mechanism. In use, the material to be welded is placed on the flat support, and a first motor and a second motor are controlled via a control panel. The first motor controls the rotation of the adjusting roller, which, supported by the support shaft, rotates the material to be welded to adjust its angle. After the angle adjustment is complete, the second motor starts, driving the linkage gear to rotate via the drive gear set. Simultaneously, the synchronous pulley rotates, driving the other synchronous pulley via the synchronous belt, thus driving the double-end self-clamping mechanism on both sides. Driven synchronously from the bottom, the double-end self-clamping mechanism causes the extension block to rotate, pulling the connecting rods on both sides. These connecting rods simultaneously pull the flexible limiting clamps to move towards the center position until they contact both sides of the material to be welded and clamp it, at which point welding can begin.
[0018] Through the above settings and processes, the equipment can automatically clamp materials using the drive gear set and the double-end self-clamping mechanism. Compared to existing adjustable welding roller frames, it adds a linear flexible clamping effect while retaining angle adjustment, allowing the welded material to remain in a fixed position even when the machine tool vibrates, preventing displacement of the welding position. Furthermore, the linear clamping operation is fast and more adaptive, eliminating the need for slow adjustments to the placement dimensions at the center using a screw. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] In this embodiment: an adjustable welding roller frame includes a workbench 1, a control panel 2, a flat support 3, and a first motor 4. The control panel 2 is located on the outside of the workbench 1, the flat support 3 is located on the upper end of the workbench 1, and the first motor 4 is located inside the flat support 3.
[0026] An adjusting rubber roller 5 is provided on the side of the first motor 4, a support shaft 6 is provided on the side of the plane bracket 3, a drive gear set 7 is provided at the bottom of the worktable 1, and a double-end self-clamping mechanism 8 is provided below the plane bracket 3.
[0027] The double-ended self-clamping mechanism 8 also includes an extension block 801, a connecting rod 802, and a flexible limiting clamp 803. The extension block 801 is fixedly connected to the side end of the double-ended self-clamping mechanism 8, the connecting rod 802 is inserted into the side end of the extension block 801, and the flexible limiting clamp 803 is movably connected to the other end of the connecting rod 802.
[0028] In this embodiment, two sets of extension block 801, connecting rod 802 and flexible limiting clamp 803 are provided, and they are evenly distributed on both sides of the double-end self-clamping mechanism 8. The flexible limiting clamp 803 has an inwardly concave arc surface structure on the opposite side. The planar support 3 has a rectangular block structure at the position where the flexible limiting clamp 803 contacts, and the rectangular block is embedded in the bottom of the flexible limiting clamp 803.
[0029] Specifically, such as Figure 1 and Figure 3 As shown, the flexible limiting clamp 803 with an inner arc surface structure can fit the outer edge of the tubular welding material, thereby improving stability, while the rectangular block structure at the bottom of the flexible limiting clamp 803 can keep the stroke of the flexible limiting clamp 803 fixed during translation.
[0030] In this embodiment, the drive gear set 7 further includes a linkage gear 701, a synchronous pulley 702, a synchronous belt 703, and a second motor 704. The linkage gear 701 has a shaft structure in the middle, and the linkage gear 701 is movably connected to the bottom of the double-end self-clamping mechanism 8 near the second motor 704 through the shaft structure. The synchronous pulley 702 is fixedly installed on the upper end of the linkage gear 701, and there are two sets of synchronous pulleys 702. The synchronous belt 703 is sleeved around the two sets of synchronous pulleys 702. The second motor 704 is movably connected to the bottom of the drive gear set 7.
[0031] Specifically, such as Figure 2and Figure 4 As shown, the linkage gear 701 transmits the driving force of the second motor 704 through the meshing of the tooth groove with the drive gear set 7, and synchronously drives the synchronous pulley 702 and the synchronous belt 703, so that the double-end self-clamping mechanisms 8 on both sides can clamp synchronously.
[0032] In this embodiment, a rectangular groove structure of equal depth is provided at the position opposite to the flexible limiting clamp 803 on the side end of the planar support 3; two sets of double-end self-clamping mechanisms 8 are provided, wherein the double-end self-clamping mechanism 8 away from the second motor 704 and the synchronous wheel 702 establish an active connection relationship with each other.
[0033] The working principle and usage process of this utility model are as follows: When using this equipment, the material to be welded is placed on the flat support 3, and the first motor 4 and the second motor 704 are controlled by the control panel 2. The first motor 4 controls the rotation of the adjusting roller 5, which, supported by the support shaft 6, causes the material to be welded to rotate and adjust its angle. After the angle adjustment is completed, the second motor 704 starts, driving the linkage gear 701 to rotate through the drive gear set 7. At the same time, the linkage gear 701 rotates, and the synchronous pulley 702 rotates, driving the synchronous pulley 702 on the other side through the synchronous belt 703, thereby driving the double-end self-clamping mechanism 8 on both sides. After the double-end self-clamping mechanism 8 is driven synchronously from the bottom, the extension block 801 rotates and pulls the connecting rods 802 on both sides. The connecting rods 802 on both sides simultaneously pull the flexible limiting clamp 803 to move towards the center position until they contact both sides of the material to be welded and clamp it. At this time, welding can begin.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
